802.11 b/g/n Wi-Fi OEMs Module, Tx-Rx, Server Type, Pin Reset

Ordering Code: CMP-R-S04-S [add_to_cart sku=CMP-R-S04-S]

The Compact-S-485 is plug-and-play stackable Wi-Fi module. It is a RS485 to Wi-Fi Converter.

The Compact-S-485 is server type Wi-Fi module. It is characterized by the capability to create a Wi-Fi network with its own IP factory editable and allow other Wi-Fi devices to connect to it.

Just a few configuration steps a quick and easy process, using our SW-Configurator issued free of charge to transfer and receive signals from the serial port, with an external RS485 transceiver, of the host device and the wireless network TCP/IP.

Thanks to its compact size and extremely low power consumption, it is perfect for mobile applications such as wireless activity monitoring, sensors and portable devices battery. With modules Compact-S-485 implements the concept of Internet-of-Things.


Compact-S-485 permits, through an external RS485 transceiver, to enable the transmission PIN of the RS485 communication.


The Compact-S-485 modules are immediately ready to be used.

Thanks to Wiicom configurator software (Compact Ready Go), available on wiicom website, user can define all Wi-Fi network settings.

There’s no need to develope or modify any software on the host board.


Wiicom offers to the evaluator a COMPACT-EVB board, which together with your Compact-S-485 in a few minutes, industrial devices will connect on Wi-Fi, eliminating time hardware and software development.

Compact-S-485 is a module of very small dimension (42 x 23 x 5 mm), characterized by a very low power on which a TCP / IP module, a micro processor and an antenna are incorporated.

Through simple accessories it's possible to evaluate the features and performance of all modules WIICOM Family Compact, linking them to various interfaces on board electrical devices for industrial use, handling analog signals, digital signals and the most common data bus.
Electrical Interface RS485 0-5V / 0-10V / 6-28V (with accessories) / 0-20mA / 4-20mA (with accessories)
Data Protocol UART direct - MODBUS
Connectivity Wi-Fi is ready after few configuration steps using an intuitive PC-interface (available for Windows and Linux OS). The accessories currently available matching family of Compact modules are the following:

Strip Adapter 8-pin

The Strip Adapter 8-pin module is used to immediately connect the Compact-Family modules to customer's device. Strip 8-pin Vertical, 8-pin Horizontal and 8-pin with holes are available.


The PWR-F-RS485 board is used to transform the Compact-485 into an RS485 compatible Device.

screen-dashboardThe Drag&Drop Dashboard (read more ...) is available bundled software to implement a customizable dashboard. Available widgets are typical environmental gauges and can be positioned into the dashboard in a drag&drop way. Drag&Drop Dashboard is able to visualize a set of signals with custom widgets directly chosen by the user. With Drag&Drop Dashboard, OEMs and System Integrators will be able to create your own custom application and prototypes for the monitoring of their devices. Drag&Drop Dashboard is available on PC version and on mobile (iOS and Android) version.
